Cote d'Ivoire joined the Artemis Accords on September 24, 2026, during the Africa Space Expo ASPEX 2026 in Abidjan. Minister of Higher Education and Scientific Research Adama Diawara signed the agreement, marking the nation as the 75th signatory. The country has collaborated with NASA on Earth observation and geodesy since 2019 and established its own space agency in 2025.

San Marino became the 76th participant on September 25, 2026, with the ceremony held in Rimini. Minister of Industry and Technological Research Rossano Fabbr signed the document. While San Marino lacks existing space infrastructure, NASA confirmed the nation is exploring future involvement in lunar projects. Deputy NASA Administrator Matt Anderson noted that participants may contribute via scientific instruments and technology.

The Artemis Accords were launched in 2020 by NASA and the US State Department alongside seven initial countries. The framework establishes principles for transparent and peaceful exploration of the Moon and Mars. Signing the agreement does not guarantee automatic funding or participation in specific missions, but it formalizes adherence to the established guidelines and enables future cooperation.
